BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a multimedia video and audio playing device usable with various playing appliances, more particularly one, which includes a main part with a built-in wireless transmission module, a wireless receiver, and various connecting members for connecting various playing appliances to the main part; thus, video and audio signals of a playing appliance can be transferred to the main part and played out after the playing appliance is connected to the main part with the help of one suitable connecting member.

2. Brief Description of the Prior Art

Video and audio players are getting smaller in size, and quality of output sound and images higher with progress of electronic technology, satisfying the consumers' need.

Home VCD and DCD players, portable CD players, portable tape players, iPOD, radios are among the currently existing video and audio players. Even desktop and laptop computers can be used to play out sound and images. Sound exists in wav format in the early days, which is gradually replaced by mp3 format because mp3 has a greater compressibility and takes up less storage space. And, portable multimedia players (PMP) are getting more common with ever increasing data capacity and size reduction of storage devices.

Portable multimedia players are easy to carry because they are small-sized and light-weighted. However, it is difficult for the elderly to clearly see the characters and images on the relatively small display screen of a portable multimedia player. Further, because the users have to wear earpieces in using the portable multimedia players, they are prone to hearing damage even though the volume of the sound output from the portable multimedia players is low.

SUMMARY OF THE INVENTION

It is a main object of the invention to provide an improvement on a multimedia video and audio playing device to overcome the above problems. The multimedia video and audio playing device of the present invention includes a main part, a wireless receiver, and a connecting member. The main part has a built-in wireless transmission module, and a holding room thereon, in which the connecting member is received in a separable manner. The connecting member has a holding space thereon, on which a playing appliance is fitted. The main part allows various connecting members to be connected thereto, which connecting members are provided for supporting various playing appliances with different dimensions and different functions. Various sockets for image transfer and various transfer wires are provided on the main part for allowing the multimedia video and audio playing device to be used with various playing devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, a preferred embodiment (A) of a multimedia video and audio playing device usable with various playing appliances includes of a main part 1, a wireless receiver 12, and a connecting member 2. The main part 1 has a built-in wireless transmission module, and a holding room 11 thereon for receiving the connecting member 2.

Referring to FIGS. 1, 3 and 4, the main part 1 has a fitting space 111 as well as an elastic transferring piece 112 in the holding room 11, a receiving hole 113 on a vertical side next to the holding room 11, and a socket 13 for image transfer. A pressed element 114 is received in the main part 1 so as to be adjacent to the receiving hole 113, and sticks out at an upper end thereof. The pressed element 114 is biased by means of an elastic element 115 so that the pressed element 114 will return to its original position when a user stops pressing it. The pressed element 114 has a hooked portion 116 facing the receiving hole 113. Furthermore, the main part 1 has a holding seat 15, charging portions 151 on the holding seat 15, an operational button 16, and a key 17 operable for turning on power supply as well as for choosing the frequency.

The wireless receiver 12 can be a headset with built-in wireless receiving module for receiving signals from the wireless transmission module of the main part 1. And, the wireless receiver 12 can be charged with the help of the charging portions 151 of the main part 1 when it is positioned on the holding seat 15 of the main part 1.

The connecting member 2 has a holding space 21 on an upper side thereof for a playing appliance to be fitted in. Furthermore, the connecting member 2 has a transferring terminal 211 in the holding space 21, an L-shaped hook portion 212 and a touching portion 213 on a bottom thereof, and an insertion plate portion 214 with a through hole 215.

Referring to FIGS. 4 to 6, to fit the connecting member 2 in the holding room 11 of the main part 1, first the L-shaped hook portion 212 of the connecting member 2 is inserted in the fitting space 111 of the main part 1. Next, the connecting member 2 is slid forwards so that the L-shaped hook portion 212 is hooked over a lower portion of the main part 11, and the insertion plate portion 214 is received in the receiving hole 113, and the pressed element 114 engages the insertion plate portion 214 with the hooked portion 116 thereof passing through the through hole 215; thus, the connecting member 2 is firm, and prevented from separating from the main part 1 owing to the L-shaped hook portion 212, the insertion plate portion 214, and the hooked portion 116 of the spring-biased pressed element 114; the connecting member 2 can be slid rearwards and separated from the main part 1 after the pressed element 114 is depressed for the hooked portion 116 to be apart from the through hole 215 of the insertion plate portion 214. When the connecting member 2 is fitted on the main part 1, the touching portion 213 will touch the elastic transferring piece 112 of the main part 1.

Referring to FIGS. 3, 4 and 7, a multimedia video and audio playing appliance 3 such as MP3, MP4, ipod, and cellular phone is inserted in the holding space 21, and connected to the transferring terminal 211 of the connecting member 2 at the elastic transferring piece 112; thus, video and audio signals can be transferred from the playing appliance 3 to the main part 1 through the touching portion 213 and the elastic transferring piece 112. Next, the signals are transmitted from the wireless transmission module of the main part 1, and received through the wireless receiver 12. Therefore, the user is allowed to receive the video and audio signals with the help of the wireless receiver 12. And, a displaying equipment such as TV can be connected to the socket 13 (for image transfer) of the main part 1 for presenting images and sound. Furthermore, the wireless receiver 12 can be charged through the charging portions 151 when it is supported on the holding seat 15 of the main part 1.

Referring to FIG. 8, a second preferred embodiment of a multimedia video and audio playing device usable with various playing appliances includes a main part 1, a wireless receiver 12, and a connecting member 2. The connecting member 2 and the main part 1 are connected in the same way as those of the first preferred embodiment. The connecting member 2 has a holding space 21 for receiving a playing appliance 3, which can be equipped with any one of currently existing different connecting interfaces. The main part 1 has a transfer wire 14 therein, which is provided for connection with the playing appliance 3; thus, when the playing appliance 3 is connected to the transfer wire 14, information in the playing appliance 3 can be transferred to and played out through the wireless transmission module of the main part 1, and sound can be played out through the wireless receiver 12. Furthermore, the main part 1 has a key 17 thereon, which is operable for turning on power supply as well as for choosing frequency of the wireless transmission module of the main part 1 and that of the wireless receiving module of the wireless receiver 12.

The main part 1 allows various connecting members 2 to be connected thereto, which connecting members 2 are provided for suiting various playing appliances with different dimensions and different functions. And, the wireless receiver, various sockets for image transfer, and various transfer wires are provided on the main part therefore the multimedia video and audio playing device of the present invention is usable with various playing appliances.
